Ingredients

• Flank Steak: This long, thin cut of beef is known for being flavorful, but chewy. Slow cooking the flank steak for fajitas lets the fat render making the meat becomes incredibly tender. You could also use a skirt steak, sirloin, or round cut of beef for this fajita steak recipe.
• Yellow Onion: Add a little sweetness with thinly sliced yellow onions. The pungent flavor of these onions mellow as they cook. Red onions are also a great option for fajitas. 
• Bell Peppers: Slice red, yellow, or orange bell peppers to add into your fajitas. Use one color, two, or all three to add a sweet flavor and some color to the dish. Be sure to include green bell peppers as well! They have a more zippy flavor than the other colors and are a must in fajitas.
• Canned Diced Tomatoes with Chilies: A can of these flavorful tomatoes adds acidity and spice to the fajitas, just be sure to drain all of the excess juice before adding them to your slow cooker.
• Chipotle Peppers in Adobo Sauce: These peppers add an earthy, smoky, and spicy flavor to any Mexican-inspired dish. You only need a little bit to pack a punch!
• Garlic: Fresh garlic adds a zesty, aromatic flavor to the fajitas. Mince the garlic yourself or buy a jar of preminced garlic at the grocery store.
• Lime Juice: Fresh lime juice adds brightness and acidity to this dish. The acidity helps tenderize the steak and meld the flavors together.
• Seasonings: Create a fajita seasoning using chili powder, cumin, paprika, oregano, salt, and pepper, or use a packet of fajita seasoning.

Variations

• Use Chicken Instead: If you don't eat red meat, or simply aren't in the mood for steak fajitas, try chicken fajitas instead. Use boneless skinless chicken breasts or thighs to avoid any bones. Slow cooker chicken fajitas only need to cook for 3.5-4 hours, rather than 6-8 hours.
• Sweeten the Sauce: If you want to balance the spicy and savory flavors with a little sweetness, add a bit of honey or agave nectar to the crock pot. 
• Add More Veggies: Create a well-balanced meal right in the crock pot and add more vegetables! Mushrooms, carrots, and cauliflower are great options because they take longer to cook and won't get mushy in the slow cooker. You could also add a can of beans or corn. 
• Spice It Up: While the chipotle peppers in adobo sauce and chilies add a little spice, you can make these crock pot steak fajitas a little spicier with fresh or pickled jalapenos.

How to Make Slow Cooker Steak Fajitas

You'll never feel intimidated by fajitas again after you try these crock pot flank steak fajitas! They are so simple, require hardly any prep work, and are delicious.

1. Step 1: Add the Onions and Peppers. Slice your onions and peppers and add them to the bottom of a 6-quart slow cooker.

2. Step 2: Place in Slow Cooker. Place the flank steak on top of the vegetables and season with chili powder, cumin, paprika, salt, oregano and black pepper.

3. Step 3: Top with Tomatoes. Add the drained tomatoes and chilies, adobo chipotle peppers, garlic, and lime juice to the slow cooker. 

4. Step 4: Let It Cook. Secure the lid and set to low. Let the flank steak fajitas cook for 6-8 hours.

5. Step 5: Slice and Serve. Once cooked, remove the flank steak from the crock pot and let it rest on a cutting board for a few minutes. Then slice it into thin, less than 1 inch, strips against the grain of the meat. Mix the cut meat back into the sauce, then serve using a slotted spoon.

Storage Directions

• Storing: Store any crock pot steak fajitas in an airtight container in the refrigerator for up to 3 days. You can also freeze them for up to 3 months in a freezer-safe container. Include a little bit of the juice when storing to keep the meat from drying out and getting tough.
• Reheating: Reheat these steak fajitas in a skillet on the stove with the juice over medium heat for 20 minutes, or until heated through. You can also heat them in the microwave under a damp paper towel for 30 second increments until heated through.
• Make Ahead: Make these fajitas in the crock pot and store them in the freezer for an easy freezer meal during busy weeks. Just be sure to slice the meat before you store them because a whole flank steak will take forever to defrost and reheat!
